Yeah, I hear that. I was pretty frustrated with winning all the bandit battles and then losing all the items I had afterwards in a cutscene of all things which we have no control over. I was like, WTH?!!! After visiting the dev's Discord channel and discussing it with others, apparently in earlier versions of the game, you would even lose your deck after this part of the story but enough players had vented their frustrations to the developer about it that the dev altered the game so we wouldn't lose our deck as well at that point in later versions of the game.
I think I stated earlier in this forum that I would have been up for them leaving it that way though, with us even losing our deck because like I said just earlier, we don't necessarily have to let that be the case as long as one has the Freedom in Death card, you can get around this. Obviously, one would have to had obtained one of those cards to get around it but to me, that would mean we (us players) were using our heads to navigate around a most likely intended effect that the dev wanted us to incur with the story at that point but in actuality there is a way to circumnavigate it. Doubt the dev actually created the Freedom in Death card just for us to use it here as we will miss seeing the cutscene altogether if you do end up using like I did here because you never do get to see the scene with the Bandit Leader doing so.
I just think if you have been enjoying the game up until now though, particularly the card game battle portion of it as you don't see this too often in adult VN games along with a good storyline as well, you may be losing out ultimately here with the hardline stance that you've taken with this one aspect of a game you are otherwise enjoying. However, I understand at the end of the day, if it's something that turns you off to that degree, you stand by that principle instead.
